DEVICE FOR UNLOADING, RECHARGING, AND RELOADING ELECTRIC-CAR STORAGE-BATTERIES.

SPECIFICATION forming part of Letters Patent No. 433,851, dated August 5, 1890.

Application filed April 24, 1890. Serial'No. 349,398. (No model.)

To all whom it may concern:

Be it known that I, JACOB CHESTER CHAM-,

BERLAIN, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Devices for Unloading, Recharging, and Reloading Electric-Oar Storage- Batteries, of which the following is a specification. 1

This invention relates to those systems of electric traction in which the current is derived from storage-batteries or accumulators located upon the car itself, the purpose of the invention being to enable the substitution of charged for exhausted batteries in the most expeditious, economical, and effective manner possible.

This application comprises certain improve-, ments on the invention described in my application, Serial No. 317,008.

Referring to the accompanying drawings, which form a part of this specification, Figures I and II are respectively end and side elevations, p'artly'in section, of my improved battery-rack and related features of improvement.

Each slip or charging-stall combines the following instrumentalities:

1 1 represents a pair of rails of an ordinary street-car track or a branch thereof.

2 represents part of the running-gear of a street-car, and 2 2", respectively, represent parts of the bed'or body and of abed-sill. The spaces under the seats are utilized in the customary way as receptacles or closets 3 to receive and hold batteries 4, which when housed within said closets are coupled up with each other-and with the motor in any approved way.

The rack shown in the present application has several features in addition to those described in my former application, which features relate to extending the capacity of the rack and facilitating the shifting of the batteries.

The batteries from the car are run across the bridge 47 and through the compartments of the inner rack, which is on a level therewith, onto the elevator or carrier 12 12', which carries them to the shelf whereto they are to be transferred. The inner racks 43 44 are provided with rests 46 for the draw-bridges 47.

To enable the operator to have easy access to the high shelves of the racks, I provide what I term the workmans platform 48, which is connected by cables 49 to the hoist or carrier in such a manner that it follows to some extent the movement of the latter, so that the workman on the platform will always be in convenient working proximity to the carrier and can easily reach the batteries on the carrier and the shelves opposite the same.

vices-such as handles 54are connected by intermediate mechanism-such as connecting-rods 55 and levers 56to-a common operating point or station 57. Oounter-i veights 58 are provided for the carriers, being connected thereto by cables in an obvious manner.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a device for unloading, recharging,

and reloading electric-car batteries, the combination, with the double rack adapted to receive and charge the batteries, of the inter posed carrier, substantially as shown and described.

2. In a device for unloading, recharging, and reloading electric-car batteries, the combination, with the battery-racks, of the battery-hoist and the workmans platform connected to and operated by the battery-hoist, substantially as shown and described.

3. The combination, with the battery-racks, of the battery-hoist, the workmans platform connected thereto, and the connection having loose motion when the platform is down, substantially as and for the purposes set forth.

4. In a device for unloading, recharging,

5 and reloading electric-car batteries, the combination, with the battery-racks, of the two hoists and the operating devices for the two hoists controlled from a single point, substantially as shown and described.

J. O. CHAMBERLAIN.
